Speed record

[holocene]

Does anyone know the record for the fastest speed ever attained, in space, by a man-made object having mass?

Fastest manmade object having mass: Helios II, 17 Apr 76, 150,000 mph here. <br /> <div class="Discussion_UserSignature"> <p> </p><p> </p> </div>

Awesome link, thanks.<br /><br />150,000mph = 41.6 miles per second!<br /><br />Unfortunately, even at these speeds, it's going to take 4,474 years just to reach the nearest star.<br /><br />One has to wonder how/if humanity will ever find a way to explore the galaxy and beyond. If FTL really is impossible, I doubt we ever will.

We can colonize the galaxy in some millions of years with Orion nuclear impulse propulsion.<br /><br />Campare that to the mess humans have made here in the last 3 million years . . .<br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

FTL travel is fiction.Nothing can travel faster than light.As per General theory of relativity.We shold know this theory to make proper use of the board.

The article you posted is now incorrect for interplanetary vehicles. After its recent gravity assist from Jupiter, New Horizons is now traveling at circa 50,000 mph. If memory serves, that is about 15 times faster than a rifle bullet.
